How to read this profile

No universal OCuLink face-view numbering is published in V40; exact variant identification is required first.

Source-scoped identification facts

Each value retains its exact example, role and measurement axis. Facts from different parts must not be combined into an invented component.

Unknown fields stay unknown; illustrations supply no measurements or pin assignments.

Recorded variant and source limits
  • Exact OCuLink/NPIO lane count and circuit count must be identified from the specific variant; the family name alone is insufficient.
  • No universal face-view numbering, fabrication geometry or protocol-generation guarantee is published.
  • Passive/active latch options describe retention, not an actual polarization feature. Recorded source context: Cable-side passive or active latching options / null

Unknowns stay unknown.

  • Exact OCuLink/NPIO lane count and circuit count must be identified from the specific variant; the family name alone is insufficient.
  • No universal face-view numbering, fabrication geometry or protocol-generation guarantee is published.

Claims and sources

Molex documents Nano-Pitch I/O / OCuLink variants with multiple lane sizes and circuit counts, so V40 does not collapse OCuLink into one universal contact count.

Molex documents Nano-Pitch I/O / OCuLink variants with multiple lane sizes and circuit counts, so V40 does not collapse OCuLink into one universal contact count.

Claim scope: V40 engineering-reference fact only; independent human review remains pending. This claim does not approve fabrication, rewiring, substitution, electrical safety, protocol support or end-to-end compatibility.
